Addressing the unaddressed

Cooling and air conditioning is a key energy consumer worldwide.

All commercial cooling units sold are based on electricity as main energy input and apply industrial refrigerants with high global warming potential.

No option for consumers for selecting Green product types.

Cooling market essentials

I. 140mio. a/c units sold globally in 2015 with 8%annual growth rate

II. EU market size 2015 of 6,5mio. units/year

III. 80% of systems sold have capacity <5kW

IV.Split type systems hold market share of 84% systems dominate market in global and EU market

Instant district cooling - a green business opportunity

● District heating network & PURIX splits offer an instant access to district cooling market without investment in additional infrastructure

● Air cooled multi split absorption systems target the high volume market segment for cooling and a/c (2,5kW – 10kW)

● Improves utilisation of existing district heating networks and energy utilisation from waste incineration, solar thermal, waste heat and CPH plants

● Competitive district cooling overcomes market enrry barriers by applying

● ’off-the-shelf’ and plug&play cooling systems● Recognizable product design concept (air cooled multi split)

How it Works

1 Evaporator The evaporator produces chilled water by evaporating refrigerant (water) at low pressure. The vapor generated byevaporation flows towards the absorber. The chilled water is distributed for cooling purposes in fan coils.

2 Absorber The vapor from the evaporator is absorbed into a strong saline solution. The absorber is cooled by a fan. After absorption of the vapor, the weak solution returns to the generator.

3 Generator The generator heats a weak saline solution, producing vapor. Vapor flows into the condenser while the stonger solution returns to the absorber. In a Purix system, the generator is heated by solar collectors, or from a backup heating source.

4 Condenser The air cooled condenser receives water vapor from the generator and produces liquid water which flows to the evaporator.

5 Expansion The liquid produced in the condenser flows towards the evaporator, passing the expansion valve which reduces pressure and thus evaporation temperature.
